1. Search for sources of resistance to Meloidogyne enterolobii in commercial and wild tomatoes
RESUMO Meloidogyne enterolobii (=M. mayaguensis) é um patógeno de plantas capaz de induzir galhas e reduzir produtividade de uma vasta gama de espécies hospedeiras. Este patógeno tem sido também reportado como ameaça global para a cultura do tomateiro (Solanum lycopersicum), principalmente, por causa da sua habilidade de suplantar a resistência a algu

2. REACTION OF Crambe abyssinica TO Meloidogyne javanica AND M. incognita RACE 3
RESUMO Dentre todas as oleaginosas que estão sendo pesquisadas atualmente no Brasil para produção de biodiesel, o crambe, Crambe abyssinica Hochst, vem se revelando como uma das mais promissoras. Neste trabalho estudou-se a reação de crambe aos fitonematoides Meloidogyne javanica e M. incognita raça 3, em casa-de-vegetação. Para os ensaios adotou-se

3. Resistance of sweet potato clones to meloidogyne incognita races 1 and 3
The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm

4. Management of Root-Knot Disease on Tomato with Bioformulated Paecilomyces lilacinus and Leaf Extract of Lantana camara
Glasshouse experiments were conducted to evaluate the efficacy of application frequency of a bioformulated Paecilomyces lilacinus in combination with five concentration of Lantana camara crude aqueous leaf extract against Meloidogyne incognita race I on tomato. The experiment was a 3x5 factorial laid out in a completely randomized design (CRD) with four repl

5. RESISTÃNCIA DE CULTIVARES DE FEIJÃO E FEIJÃO-VAGEM AOS NEMATOIDES DAS GALHAS / Resistance of bean and snap bean cultivars to root-knot nematodes.
The objective of this work was to assess the reaction of field and snap bean cultivars to the infestation by Meloidogyne incognita races 1 and 3 and Meloidogyne javanica. Three independent experiments to each species and race of Meloidogyne with four replicates and four plants per plot were conducted. In each block, a plot with the susceptible tomato cultiva

6. Parasitismo de Meloidogyne spp. em plantas nativas do oeste paranaense e variabilidade genÃtica de populaÃÃes de Meloidogyne incognita raÃa 3 / Parasitism of Meloidogyne spp. on native plants in Western ParanÃ, Brazil, and genetic variability among populations of Meloidogyne incognita race 3
The aim of this work was to study the parasitism of Meloidogyne incognita on native plants from Western ParanÃ, Brazil, as well as to assess the genetic variability among different populations belonging to the race 3 of this nematode by RAPD technique. Natural infection was studied in thirty six native plant species, which were identified on the basis of th

7. Desenvolvimento de marcador molecular para resistência a Tobacco mosaic virus e herança da resistência a Meloidogyne incognita raça 3 em tabaco / Development of molecular marker for resistance to Tobacco mosaic virus and heredity of resistance to Meloidogyne incognita race 3 in tobacco
The aim of this study is to develop a molecular marker linked to the resistant gene to Tobacco mosaic virus (TMV) considering the necessity to improve plant breeding to meet growing demands of productivity. The other goal of this study is to evaluate the mode of inheritance of an F2 segregating population and backcross (BCF1) population of Meloidogyne incogn

8. Levantamento de Meloidogyne incognita em lavouras de algodÃo no noroeste do Paranà e seleÃÃo de genÃtipos de algodoeiro com resistÃncia a Meloidogyne incognita raÃa 3 / Survey of Meloidogyne incognita on cotton crops in northwest Paranà and selection of resistant cotton genotypes to Meloidogyne incognita race 3
Among the pathogens that reduce the cotton productivity in Brazil, Meloidogyne incognita is one of the most important by causing yield losses and for being widespread. The most recommended control methods to this species are the use of resistant cultivars and crop rotation systems. In ParanÃ, M. incognita races 3 and 4 have already been reported as cotton p

9. Pratylenchus coffeae em cafeeiros: efeito de densidades populacionais do nematóide e testes com genótipos. / Pratylenchus coffeae in coffee plants: effect of initial population densities and tests with genotypes.
The lesion-nematode Pratylenchus coffeae is a major pest of coffee and other economic crops and its biological variability, which often makes difficult the adoption of control methods, contributes to increase the importance of this parasite in Brazil. Due to the importance of coffee production and the lack of studies involving this nematode species in Brazil

10. Alterações fisiologicas no algodoeiro causadas pelo nematoide Meloidogyne incognita raça 3 : influencia do nivel de inoculo e do fornecimento de nitrogenio
Growth and variation in the contents of soluble sugars, phenols and chlorophyll, and nitrate reductase activity were determined in cotton plants (Gossypium hirsutum) of cv. Acala (susceptible) and cv. IAC-20 (tolerant) inoculated with eggs (O, 500 e 5.000) of Meloidogyne incognita race 3. In a second experiment the same parameters were also determined in pla

11. Repeated sequence sets in mitochondrial DNA molecules of root knot nematodes (Meloidogyne): nucleotide sequences, genome location and potential for host-race identification.
Within a 7 kb segment of the mtDNA molecule of the root knot nematode, Meloidogyne javanica, that lacks standard mitochondrial genes, are three sets of strictly tandemly arranged, direct repeat sequences: approximately 36 copies of a 102 ntp sequence that contains a TaqI site; 11 copies of a 63 ntp sequence, and 5 copies of an 8 ntp sequence. The 7 kb repeat
